Oxford United could not pull off an FA Cup upset as they fell to a 3-0 defeat against Sheffield United this afternoon.

Tony McMahon broke the deadlock in the 17th minute with a right-footed shot from around 20 yards out.

However, the Blades had to wait until 20 minutes from time to double their lead, with Dave Kitson duly obliging from six yards out.

Top scorer Nick Blackman completed the scoring in the dying minutes, confirming that Sheffield United's name will be in the hat for the fourth-round draw.
